Application filed October 24,1221, Serial no. 509,854.

To all whom it may concern: 7 V Be it known that I, RUDOLF R; Raninsn; 'a citizen of the United States, residing at leveland, in the county of Cuyahoga and State of @hio, haveinvented-certain new and useful Improvements in Rotary Brushes, of which the following is a specification. This invention relates. to rotary brushes, and particularly to the means for fastening the brush material or strands .to the central part of the brush. Various means have been heretofore provided for attaching the wire strands or bristles to the body of a rotary brush, and some of these involve twisting the strands. The present invention avoids twisting of the strands, and em bodies a construction by means of which the various bunches or tufts of strands are assembled on a body member or ring by the use of clips which engage and hold the strands, the strands being doubled around the ring so that they cannot become loose.

The manner of construction of the brush will be more fully apparent tromthe following description and the accompanying drawings in which Figure 1 is a plan of the brush body. 22 of Fig. 1. Fig. 3 is aplan of the body ring. Fig. 4 is a perspective view of one of the clips in the form of a slitted blank. Fig. 5 is a perspective of the blank with tongues bent up before the strands are applied thereto.

It is to be understood that the drawings show the brush body which when completed will be assembled upon a spindle ordinarily between two side plates which are not shown as they form no part of the invention, and the body'may be supported upon a hub or spindle in various ways. In the drawings, 6 indicates a sheet metal ring the inner edge of which is provided with a series of spaced notches 7, and holesv 6* between said notches. This ring may be readily stamped out of sheet metal. The strands of brush material are indicated at S, and these strands are arranged in bunches each of which is held by a clip consisting of a metal plate 9 which is slitted as at 10 to form two pairs of tongues 11 and 12, the respective tongues of each pair being located at opposite ends of the plate and being bent upwardly from the plane of the plate in opposite directions, as clearly shown in Fig. 5. This clip has a depression Fig. 2 is a section on the line 9 therein, and the clip may also be conveniently cutand'stampod from sheet metal. The-bunches ortu'iits held by the respecillVB QllPS llG assembled around the ring 6 to make a complete brush.

"A m. t assembling may be as follows. it cup 9 is applied to one side of the r ng 6, and flatly against the same, .with the tongues 11 tending through two ot the notches 7, and the 'depression'ti extending into the holes 6, this will correctly position the clip and also serve as a means to prevent movement thereof. lied and is bent around the ring'and also around the body 9 of the clip, said body and the corresponding portion of the ring being enclosed between the brush material, as clearly shown in Fig. 2. The tongues ll and 12 are then bent or pressed down against opposite sides of the brush material, whereby said brush material is clamped and held to the clips and the clips are also held in position on the ring. The clips maybe further fastened to the ring by a spot weld between the outer edge of the clip and the outer edgeofthe ring, as indicated at 14-. A suflicient number of clips and tufts or brushes are assembled on the ring in the manner indicated, to complete a circular 1: rush, the tongues 11 oil each clip extending through the notches. 7 in the manner described. @rdinarily the ends of the tongues 11 and 12 will lap each other when they are pressed down upon the strands in the man ner indicated. This provides a very lirm fastening for wires or other brush material without the'twisting abovereiierred to.

I claim:

1. A brush comprising a ring, a series of clips around said ring, said clips having bent tongues projecting laterally therefrom, and bunches of brush material folded around the ring and clamped by the tongues bent down thereon.

2A brush comprising a notched ring, a series oi clips around the ring and having tongues projecting through said notches, and brush material held by said tongues.

3. A brush comprising a notched ring, a

series of 'clips around the ring, having tongues extending through said notches, and

bunches of brush material folded around the ring and clamped by said tongues.

4. A brush comprising a notched ring, bunches of brush material folded around said ring, and a series of clips arranged,

Then the brush material 8 is ap- The manner of v,

around the ring and having oppositely extending tongues eiamplng said material at opposite sides of the lung.

, 5. A brush comprising a ring, bunches of brush material folded around said-ring, and a series of clips arranged around thering and having oppositely extending tongues clanipin said material at opposite sides of the ring, said ring having openings through which some 0% said tongues extend.

('3. A brush comprising airing having a series of notches in its inner edge, bunches of brush material folded around saidring, and clips having bent tongues extending tlrough said notches and clamping the brush material.

7. A brush comprising a ring clip plates arranged around said ring and having proectmg tongues at opposite sides thereof,

and bunches of brush material folded around said ring and plates, the tongues behent down upon said material at oppo site sides of the ring. 7

I A brushconiprising a sheet metal ring having a series of notches in its inner edge, elip plates arranged around said ring and having pairs vof= oppositely projecting tongues, the tongues ofone pair extending through said notehes,xand bunches of brush material folded around said ring" and plates 'the tongues being bentwlown'upon said hunches atopposit-e sides of therlng,
